reordering structure based on the content of one field

if there is a structure (S) for 10 nodes. the three fields of the structure are (xd , yd and ID) where,,

S.xd ==> X-dimension , S.yd ==> Y_dimension , S.ID ==> node's order or its ID , S.E ==> Energy

I wanna reorder the structure of these nodes based on their residual energy

Maybe this:

se = [S.E]; % String together all S.E items.
% Now sort in ascending order
[sortedSE, sortIndexes] = sort(se, 'ascend');
% Now sort the structure array.
S = S(sortIndexes);
